Completely pointless, you'll be lucky to gain 1/2 mpg.. WHY.. civics have a factory ELD (electronic load detector) that shuts off the voltage to the alternator field windings, which means when your car doesn't need anymore juice pumped into it the car shuts the alternator off and the only thing your spinning is the slight windage and friction losses in the alternator, not needlessly cranking out voltages..
